Entering and importing weather and crop data.
After a network has been created, crop data can be entered by hand. In principle this is possible for grid-based networks and station networks alike. However as grid-based networks do not coincide with a ground network, it will usually not make sense to enter data manually.
Entering weather data manually
As the FAO water balance model is usually run with a 10-day (dekadal) time step, this example will show how to enter dekadal data.
Activate the Database - Manage Weather Data - Dekad function. 
In this window the grid is defined. At first select the polygons in the top box and select them with the down-arrow. Then specify the grid density. In this case 0.,5 degrees is chosen. Press <Redraw> to see the result. This means that a square grid will be created where stations are half a degree apart. Please note that the program predicts the creation of 1343 stations. Specify a list name to be generated and prefixes for the station names and ID’s in order to clearly distinguish the stations in the list. 
After pressing the <Generate>, the list is filled and finally shown in the AgrometShell list editor.
